6 Claims.

This invention relates to pumps and has for its object to provide aforce pump located slightly below a small stream of water by means ofwhich it is actuated.

Another object of the invention is to provide in a pump a double leveroperated by water for actuating the pump piston.

A further object of the invention is to provide in a water pumpingsystem means for distributing a stream of water whereby a pump will bedriven by the force of said water.

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawings inwhich:

Figure 1 is a diagrammatic view illustrating my invention,

Figure 2 is an enlarged elevational sectional view of a pump housing andconnection,

Figure 3 is an enlarged detail sectional view' of a lever operatingmember,

Figure 4 is an enlarged top plan view of Figure 1,

Figure 5 is an enlarged sectional view taken it will be noted that mypumping apparatus Ill,

is located somewhat below a spring, or stream designated as A. Thedistance the apparatus is lo-' cated below the water level a, isimmaterial as long as all the operating elements of the device are belowsaid line a, in order that the water will flow freely to said elements.

The pump housing H is substantially rectangular in shape and is formedto include the vert cal walls [2, one of which supports a fulcrum 43upon which the cylinder block I4 is pivo-tally mounted. An inlet end forthe cylindrical block I4 is provided and is connected to a flexible hose5 which will be connected in any suitable manner with an elevated sourceof water supply A.

The inner ends and 2| of the relatively long lever pipes 22 and 23 aresecured to the block l4, while their outer ends 24 and 25 are secured toand support the tanks 26 and 21. Extending clean through the pipes 22and 23 and the mem ber 14, is a heavy wire rod 28, the ends 29 and 30 ofwhich project into said tanks 26 and 21. Connected to the end 29 is avalve 3| adapted to open the port 32 into tank 26 when the member 22 isin raised posi ion as indicated in Fig- 2 ure 1 of the drawings; and onthe rod end 38 is mounted a valve 33 adapted to close port 3 1 of tank21 when said tank is in its lowermost position as also indicated inFigure l of the drawings.

Pivotally mounted as at 35 in the top wall 26 of tank 26 is a gravityactuated lever 36, on the outer end 37 of which is a weight 38. Thelower and inner end 39 of the lever is pivoted at 40 to the inner end 29of the rod 28. Fixed to the extreme end 28' of said rod is a downwardlyprojecting right angularly disposed elongated pin 4! which runs throughand somewhat below a loop 42, the horizontal arm 43 of which has a rightangular end 44, the terminal of which is fixed at 45 to a flap valve 46adapted to close the outlet port 41 of the bottom wall of the tank 26.When element 22 is in raised position, the weight 38 will have thrownlever end 31 to the position shown in Figure 1 causing end 39 of saidlever to draw rod 28 inwardly of the tank 26, and outwardly of the tank21, this action causes arm 4| to push against end 42 of link 42 and thearm 44 to a position to close valve 46. In this position the valve 3| isopen and valve 33 of tank 2! closed, causing water to flow into tank2'6. This action reverses the action of like members in tank 21, pullingend 30.

of rod 28 out drawing member 48 with it and causing link 49 to draw arm50 to open the valve 5| to permit water to flow through port 52 from thetank 21. The action then again reverses and cont nues indefinitely. Asupport 53 for the rod end 30 is pivoted at 53 to the tank 21 and tosaid rod end 30.

Mounted on the lever arm 23 is a pump jack 55 p votally connected to theouter end 56 of the piston rod 51 of piston 58 operating in pumpcylinder 59. Between the spaced apart bottom walls 6!] and (S! ofhousing l l. is formed a relatively small water receptacle 52 into whichthe lower end 63 of cylinder 59 opens. Also opening into the receptacleis a water inlet pipe 54 having a goose neck from which the pipe extendsto connect at 63 with inlet 19 of member l4. Located in section 6'! ofpipe 64% is a check valve 68. One end of the outlet pipe 89 connects atill with the receptacle t2 and connects at its other end at H with thestorage tank T2. The flexible pipe 16 is connected at is to a supplypipe 14, the inlet end E5 of which opens into said water supply A.

Having now set forth and located the elements of my invention I willproceed to explain its operation. Water flows through the pipe I4 andthrough the flexible connection [6 to the distributing member l4, fromwhence it passes through the several ports thereof to pipe 64 fillingreceptacle 62 which is always full, then the water flows down throughpipe 23 now stopped by valve 33, then the water fiows up through pipe 22through open port 32 and fills tank 26, the bottom valve 45 of which isclosed. The weight of water in tank 26 causes it to drop to lowermostposition throwing crank 38 to reverse position of rod 28, therebyopening port 34 allowing water to fill tank 21. With the same action thevalve 35 is opened permitting water in tank 26 to escape, and as thistank thus becomes lighter, the heavier tank 21 goes down. This cyclecontinues indefinitely. As lever arm 23 goes up and down it operates thepump piston 58 drawing water into cylinder 59, and with it a freshsupply for receptacle 62 through pipe 64, Which pipe is then checked byvalve 58. The piston then goes down forcing its supply of water downinto receptacle 62 which is already full. thus water therefrom is forcedup into pipe 69 and on through the same and into 'tank12.

the thimble 8! and supports the end link of the,

chain -84. The-other endof the chain is linked to the valve 85eccentrically, whereby when the -end 78 is forced inwardly. thelever 8!!will rotate thimble'Sl raising hook 132 and with it the chain 84 andvalve (15. Reverse action on rod 28, of course, permits thevalve-to.close'by gravity.

.Itis .to be noted that if desired the elements 155 and 51 maybedisconnected andpipe 6'. plugged and another pipe (not shown) connectedto pipe 55, .and run tola spring whereby the pump will be operated fromthe streamA, and water to tank l2v drawn from a spring or other sourcethan said stream A.

.It is thought thatpersons skilled in the art to which the inventionrelates will be able to obtain a .clear understanding of the inventionafter considering the description in connection with the drawings.Therefore, a more lengthy description Having now described my inventionthat which I cla m as new and desire to procure by Letters Patent is:
